PACKAGING INFORMATION:
SR730 Structural Silicone Sealant is supplied in 300 ml disposable plastic cartridges and 200L drum packaging.

USABLE LIFE AND STORAGE:
When stored at or below 27°C in the original unopened containers, SR730 Structural Silicone Sealant has a usable life of 12 months from the date of production.

LIMITATIONS:
• Not suitable for use in In totally confined spaces as the sealant requires atmospheric moisture for cure
• When the surface temperature of the substrate is lower than 10 °C or exceeds 40 °C, it is not suitable for working.
• Not suitable for frosted or wet surfaces
• Not suitable for continuous flooding or wet places all year round
• Not suitable for all materials that that bleed oils, plasticizers, or solvents materials such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes
• Can not be used in horizontal floor joints where abrasion and physical abuse are likely to be encountered
• Do not contact with any sealant that may release acetic acid
• Can not be used where paint is required
• Can not be used on surfaces that are in direct contact with food

HOW TO USE:
• Surface preparation
Thoroughly clean all substrates to be bonded before using this product to remove all foreign matter and contaminants such as grease, oil, dust, water, frost, surface dirt, old sealants or compounds and protective coatings. Metal, glass and plastic must be cleaned with solvent according to two rag cleaning methods. In all cases, the solvent must be wiped clean with a clean, lint-free cloth. Do not use detergent or soap with water.
• Primer
SR730 Structural Silicone Sealant generally does not require a primer. However, if the adhesion test indicates that a primer is required, the primer is applied to the interface with a clean, lint-free cloth before applying the sealant. Apply a thin layer to the surface and allow it to dry. A test must be performed before using the sealant to determine if a primer is required.
• Accessory selection
At the bottom of the joint, open-celled polyurethane foam, closed cell polyethylene foam or polyolefin material can be used as the backer rod, and as for the shallower joint which cannot accommodate the foam rod, a low-viscosity polyethylene tape can be used to control the depth of sealant.
• Masking and tooling
To ensure that the surface of the substrate is clean and tidy after application, it is necessary to cover it with tape near the joint. Do not allow the making tape to touch the surface where the sealant will be applied. After the tooling work is completed, the cover tape should be removed immediately.

SEALANT APPLICATION:
Install gasket material or joint filler material, glass support blocks, gaskets and tape as required by the design.  SR730 Structural Silicone Sealant is continuously squeezed into the joint, and the sealant is flattened on the backing material and the joint surface with appropriate force. Tooling must be finished before skin forming. It is recommended to use a convex tool to trim the sealant surface into a concave shape. Do not use soap and water as an auxiliary material for tooling. Remove masking tape as soon as the tooling is finished.

PRECAUTIONS:
• Before using, please read the safety data sheet of this product for information on the safe use of the product.
• Avoid contact with eyes before curing. If contact with eyes, rinse with plenty of water and consult a doctor.
• Pay attention to ventilation in the construction and curing areas
• Uncured products should avoid contact with children
